Data Package is a standard consisting of a set of simple yet extensible specifications to describe datasets, data files and tabular data. It is a data definition language (DDL) and data API that facilitates findability, accessibility, interoperability, and reusability (FAIR) of data.
@roll, I'm not sure if there's still time, but wouldn't it make sense to add a dialect.namespace to specify the database schema where the table is located?
As mentioned in https://github.com/frictionlessdata/specs/issues/901, we have
dialect.sheetName
for selecting spreadsheets, but nodialect.table
for selecting tables in an SQL db.
